If the photographer hired the Waltons as models for his photos, and the Waltons signed a model release, then yes -- the photographer owns full rights.

I suspect that the Waltons hired the photographer to photograph them, the Waltons did not sign a model release (why would they?), in which case the photographer does not own the rights to these photos.

I think the photog (or his heirs) own the rights because that was the deal struck back when - he surely only charged for the prints actually delivered, not for an unlimited number of prints to be made in the future, or rights to copies eventually made by others. I could be wrong, but that's the way things worked, and still do AFAIK.

To me, at these standard settings, the only material difference I can see, besides the moiré issue, is that PN seems to have more saturated colours and slightly higher contrast than ACR. I think these issues, if you regard them as such, could be fixed in ACR without much difficulty.

PicOne: So, the question is, did Canon have this plan way back when they launched the 7D originally? How long ago would they have had to start development /R&D for a 7D2 that they decided not to, and how long have they known that firmware could be published to accomplish almost the same thing?

Will the 1dX have a IdX2, or will it be firmware? Will 5dIV be about in a couple year, or a 5dIII firmware update?

My guess is they knew it could be done, but firmware development also takes time, so they had a card up their sleeve for when they needed it.

This first step into the mirrorless world seems designed to sell lots of cameras to mainstream / occasional photogs. No surprise there. I hope they follow it up later with a slightly larger body incorporating at least an EVF (preferably a hybrid VF à la Fuji) on the left top rear of the camera (please!) and much more accessible / ergonomic manual controls.

Does setting 100% as the scale mean one dot on the screen per pixel in the image? At that setting it looks very sharp to me. Slightly soft at 200% setting. At 400% I see obvious pixellation, not surprising.
